Tools and Hardware Reviews of Magcraft NSN0640 1/2-Inch by 1/16-Inch Rare Earth Disc Magnets, 24-CountCustomer Review: Just what I needed Summary: 5 Stars
After some toying around with the Magcraft NSN0570 1/8-Inch Rare Earth Cube Magnets, 100-Count, trying to get them to hold up 2oz steel tins of spices on the fridge, I knew I needed to go with something stronger. These do the trick perfectly; one magnet even holds up a tin filled with peppercorns. For this application, I find that they pretty reliably stay stuck to the fridge and not the tin, so I don't think I'm going to need to employ glue.
These are very strong magnets and, because they're so thin, a bit difficult to separate from one another. I've found I need to employ something non-metal to slide the top magnet off and flip it up off the stack. A used Amazon gift card works well.
So far I've had no issues with breakage, as I've been careful not to let the magnets slam into things from any kind of distance. They're not toys, and I'm not sure why anyone would think they were.
